Comparison of Stent-Related Symptoms Between Conventional Double-J Stents and a New-Generation Thermoexpandable Segmental Metallic Stent: A Validated-Questionnaire-Based Study

Abstract

The ureteral stent symptom questionnaire revealed that pain, urinary symptoms index, and general health were statistically better in the Memokath group. The Memokath group significantly outperformed the Double-J stent group in terms of the light and heavy activity. In terms of future stent insertion, patients preferred the Memokath stent. In the subgroup who had experienced both stents, the Memokath questionnaire revealed improvements in the domain of pain and the lower urinary tract symptoms index, though this was not statistically significant. This may reflect the small size of the study population. There were improvements in general health and other quality-of-life parameters, and there was a tendency in favor of the Memokath.
